This is helpful, but how would one say "show us TO the Father"? If I can see how that would be said differently, I think I can absorb the rule.

@Nathan: The problem with the "personal a" is that it is very difficult to distinguish the direct object and the indirect object when they are both people. In fact, as you've already pointed out in the question, "muéstranos al Padre" can mean both "show us the Father" or "show us to the Father".
